Gantrade P-1000 and P-2000 PTMEG based Diamines

Gantrade’s P-1000 and P-2000 are oligomeric diamine curatives based on the p-aminobenzoate ester of PTMEG 1000 and PTMEG 2000, respectively. The Gantrade P-1000 is similar to Versaink® P-1000. The P-2000 is a new material, developed for applications where a lower Durometer is required. A diamine based on the p-aminobenzoate of PTMEG 650 is also available from Gantrade Corporation.

Applications of 2-Ethylhexyl Acrylate (2-EHA)

2-Ethylhexyl Acrylate (2-EHA ) is a highly versatile building block that readily copolymerizes with a wide variety of other acrylic and vinyl monomers to tailor specific high molecular weight copolymer properties for a diverse range of non-rigid applications.

PTMEG di-p-Aminobenzoate Curing Agent for Epoxy Resins

Based on its unique structural characteristics, XYLink P-1000 polyether diamine curative delivers exceptional benefits and improved performance in epoxy systems.  

The polyether backbone is PTMEG, contributing the enhancements usually attributed to this polymeric unit.   PTMEG efficiently enhances both flexibility and fracture toughness.  The p-aminobenzoate functionality has low reactivity toward epoxy moieties.  Thus, epoxy systems based on XYLink P-1000 exhibit relatively low viscosities and cure-rate control that improves casting, coating, adhesion, and impregnation in composite applications.  As a slow-reacting diamine (tetrafunctional epoxy hardener), XYLink P-1000 is effective in applications where long working times, low viscosities, substrate wettability and lower heat-build are required.

Glacial Acrylic Acid Product Overview

Glacial Acrylic Acid Monomer (GAA) is an unsaturated carboxylic acid co-monomer used as a building block to produced acid functional and crosslinked acrylic copolymers and polyacrylic acids. GAA readily copolymerizes with acrylic and methacrylic esters, ethylene, vinyl acetate, styrene, butadiene, acrylonitrile, maleic esters, vinyl chloride and vinylidene chloride. Copolymers which contain GAA can be solubilized or exhibit improved dispersions in water; the carboxylic acid moiety can be used for coupling or crosslinking reactions, and improved adhesion. GAA copolymers are used in the form of their free acid, ammonium salts or alkali salts. These polymeric uses for GAA account for approximately 45 % of the consumption of acrylic acid monomer (the manufacture of acrylate esters is the other major use).
